Hi. I tried to reproduce this issue. I assume you are talking about system message `debian-10 /etc/init.d/mysql[2465]: MySQL PID not found, pid_file detected/guessed: /var/run/mysqld/mysqld.pid` But pid file is in place and everything works well: “ls -la /var/run/mysqld/mysqld.pid   -rw-r----- 1 mysql mysql 5 Jun 24 10:41 /var/run/mysqld/mysqld.pid ”
